Sorry, should have mentioned that I already have that enabled.

That gives me some extra info:

Feb 11 11:14:07 x dnsmasq-dhcp[2278]: 3227716451 DHCPDISCOVER(eth0) 
00:25:90:d6:ac:25 no address available
Feb 11 11:14:08 x dnsmasq-dhcp[2278]: 467005255 available DHCP range: 
10.x.10 -- 10.x.250
Feb 11 11:14:08 x dnsmasq-dhcp[2278]: 467005255 available DHCP range: 
10.y.10 -- 10.y.250
Feb 11 11:14:08 x dnsmasq-dhcp[2278]: 467005255 available DHCP range: 
10.z.10 -- 10.z.250
Feb 11 11:14:08 x dnsmasq-dhcp[2278]: 467005255 vendor class: udhcp 1.12.0

but doesn't appear to log the subscriber ID.  I can't tell if its 
supposed to be logged in that case either.
